MetalLB: recommend IPVS proxy mode #772

Closed Cynerva closed 1 year ago

Cynerva commented 1 year ago

This doc change depends on a new feature, the proxy-extra-config option, that hasn't been released yet. It's set to go out with 1.27+ck2. See LP:2020059.

IPVS mode is needed to avoid this issue with MetalLB in clusters that use policy based routing on Kubernetes host machines.

IPVS mode is also documented in the kubernetes-control-plane charm doc here. The currently documented method based on proxy-extra-args doesn't work, so that page will need to be updated too, after 1.27+ck2 goes live. I'm not quite sure how to stage that now.

Although, I wonder about the placement of IPVS documentation in the charmhub doc. It feels like an advanced networking concept that could use a better home. Should it get its own how-to?

This seems fine BTW. As for charmhub, we can't stage stuff, so we'll just have to remember to update it. I think you are correct about IPVS - probably an explanation page and a how-to

I've updated the discourse post with proxy-extra-config as noted in this PR.

@Cynerva i agree with you and @evilnick that this warrants a place in advanced networking docs, but I don't think we should try to land that with this PR. That'll fit better once we get into our diataxis structure -- let's track that effort in #787.
